This stunning photo of JB (in all white — like an angel! Or a bride…) and his muscles was captured as The Biebs took the stage at 93.3 FLZ’s Jingle Ball in Tampa. Just so y’all are totally clear, one’s muscles don’t just start bulging out of nowhere, especially when you’re just sitting pretty on a wooden stool, but JB is just that ripped. The kid ain’t even trying to flex. He just does it by default. We guess it’s good that Justin’s staying on his fitness, though, since he just added a whopping 30 more tour dates to his already grueling schedule. #Stamina #Onhisgrind
